The effect of introducing stellar rotation at the base of a stellar wind outflow was investigated. Model line profiles are calculated by combining a radial and rotational motion of the wind particles, thus modifying the radial dependence of the line-of-sight velocity and the optical depth. The Sobolev approximation and the escape probability method are used. Model profiles are presented for varying amounts of V rot/V inf. The profiles thus obtained are much smoother than those where rotation is not included, particularly at line center. The discontinuity and the sharp emission peak there are eliminated without resorting to arbitrary optical depth laws. Rotation and high collisional rates produce a blue wing emission, observed in stellar and quasar spectra.
